Mavs fans are the only fans that can claim the Cowboys as thier true "home" team. All fans of other teams get thrown in the same bag. I Rockets fan for example has a "true" home team--they are called the Texans.
There are Cowboy and Laker fans everywhere though, so I can see how it could happen (not for me though).
To make things worse, I think the Lakers will pull the three-peat. sux
Unless the Mavs can upset them in round two--which I don't see happening, especially if they end up losing the home court advantage to them--I see the Lakers at least in the NBA Finals.
Did I say it sux?
